The already reported monomeric complex Co(SDZ)2bpy (1) and the novel ternary complexCo(SDZ)2(6MQ)2 (2) (SDZ = sulfadiazine; bpy = 2,2′-bipyridine and 6MQ = 6-methoxyquinoline)have been synthesized in order to study their magnetic properties. X-ray diffraction methodindicates that in both compounds the SDZ acts as a bidentate ligand coordinating through thesulfonamide and the pyrimidinic N-atoms giving raise a CoN6 coordination sphere. The complexeshave been characterized based on elemental analyses, FTIR, UV-Visible spectroscopy andthermogravimetric analysis (TGA, only for 2). Both compounds, 1 and 2, have been characterizedmagnetically and they show slow relaxation of the magnetization below 9 and 6 K, respectively.
